Last month i asked "if U.S. could build a Super Weapon, don't you think it wouldn't blow up Mars?"

Sad thing guys.. i think what the U.S. is gonna do is worse.. blowing up the the Moon.. the reason? Mining.

Exactly.. our one and only Moon is believed to have a control of most of the Earth's elements.. and think of the debris..

Tell me what you think.

I know that cars can run on 85% ethanol and 15% petroleum, but what is it that ethanol lacks that makes it impossible for them to run only on ethanol?
What are some sources of ethanol, other than corn?

Consider a ten-digit number with the following properties: each digit from 0-9 occurs in the number exactly once. The number itself is divisible by ten. If you remove the last digit, the nine-digit number so formed is divisible by nine. If you remove the last two digits, the eight-digit number so formed is divisible by eight. If you remove the last three digits, the seven digit number so formed is divisible by seven, and in general the n-digit number formed from the first n digits is divisible by n. Call any number with all of these properties Pascalian. Now the question:

Part A: List all the Pascalian numbers, if any exist.
Part B: Show, by human-verifiable proof, that such a list is exhaustive.

You may wish to make use of the following information in solving this problem: http://en.wikipedia.org/wiki/Divisibility_rule

Good luck.

I need to see a sample of the kinds of questions that are on an entrance test for pipe fitter's apprenticeship programs. My fiancee' is a nervous "test taker", so having an idea of what to expect should be helpful in easing some his anxiety.

I know it's highly improbable for there to even be an eruption this century, let alone ten centuries from now. I just want to know what would happen to the United States, based on modern weather projections what would happen if Yellow Stone were to erupt in a supervolcano. With the force and destruction that it had erupted in the previous supervolcano eruption. I want sources so I can look it up myself, so don't answer without one.
